There was a time when optics made in Rochester New York by Kodak and Bausch & Lomb were as good as or better than any on earth.
Several years ago I bought a new in the box U.S. Army surplus binocular at a pawn shop near Ft. Stewart, Georgia. I also had a WWII B&L U.S. Navy binocular made in 1944. The Army one had filters made by, I think a company named Corion or something similar.
Anyway the old WWII binocular was optically superior despite having been around for many years.
That’s the difference between army binoculars and navy binoculars. The navy ones need to be better since the things that they are looking at are usually farther away.
